Just looked at the ZDZ numbers...the 50 is 3.37lbs (about 53oz) with the ignition & plug, no battery or muffler. Sounds about the same as the BGX. They say it will run a 22 OR 23 X 10 OR 12 prop!

Looks like the ground clearance might call for a 3 blade.

Can you inagine that on a 15 or 16 pound Extra?

Are the motors in stock... NO!

Are my numbers right? I hope so...
